Do patients who are infected with drug-resistant HIV have a different CD4 cell decline after seroconversion?
Using data from the UK Register of HIV Sero-converters, we compared the rate of CD4 cell decline in antiretroviral-naive individuals with and without evidence of transmitted drug resistance (TDR). Although there was a suggestion that CD4 cell decline in the first year after seroconversion was faster in those with TDR,there was no evidence of a difference in the rate of decline thereafter. The virological and host determinants of this possible phenomenon are worth further exploration.
